Answering “what is virtual reality” in technical terms is straight-forward. Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be explored and interacted with by a person. That person becomes part of this virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform a series of actions. https://www.youtube.com/watch?v=4sBQM2atjrE&t=1s
From the different headsets we've tested, the hardware is sound and the setup is simple, but position tracking isn't as accurate as tethered headsets with external sensors or the Rift S' new outward-facing tracking cameras. Also, the Windows Mixed Reality store doesn't have as many compelling VR experiences as the Rift and SteamVR stores, though you can use SteamVR games on Windows Mixed Reality headsets, again with some software wrestling. https://www.aliexpress.com/item/Amkov-Mini-360-Video-Camera-V1-Action-Camera-Dual-Image-Stabilization-Mini-Panorama-Camera-360-Degree/32859282955.html

Virtual reality is the creation of a virtual environment presented to our senses in such a way that we experience it as if we were really there. It uses a host of technologies to achieve this goal and is a technically complex feat that has to account for our perception and cognition. It has both entertainment and serious uses. The technology is becoming cheaper and more widespread. We can expect to see many more innovative uses for the technology in the future and perhaps a fundamental way in which we communicate and work thanks to the possibilities of virtual reality. https://www.youtube.com/watch?v=APd9Nmcc3nU&t=1s

To a degree, I’ve made it sound harder than it actually is since software has compensated for much of this, but these were some of the questions I was asking when I was first learning. I then started learning that some standard editing procedures could still be done. For example, I can still create image masks in 360°. So in truth, I still stood behind the camera the whole time along with others and gear and then masked myself out with a separate cut of footage showing the empty room. And for the motion graphics, (I use Adobe software) the software has built-in accommodations for editing and viewing in the 3D space so as to create accurate graphics. So in truth, once I learned, it wasn’t that hard, but boy is it time-consuming. https://www.youtube.com/watch?v=T8WE8ueJSms&t=1s
Google and Samsung still offer phone-based VR headsets in the form of the Daydream View and the Gear VR, and even Nintendo has gotten into the game with its Labo VR Kit for the Nintendo Switch. However, these shell-like headsets, which require a phone or some other device physically inserted into them, feel like novelties next to more powerful headsets that can provide more immersive experiences. https://www.youtube.com/watch?v=gFiZ7cZcuQo&t=1s
There remains a significant amount of confusion about the differences between Virtual Reality, Augmented Reality and Mixed Reality. (Check out our exhaustive primers on Augmented Reality and Mixed Reality for an in-depth look at the differences.) The public seems to think that AR is a phone experience, while only VR requires an HMD. Mixed Reality devices like the Microsoft Hololens use a headset to overlay 3D imagery on top of the real world. Very cool, but not Virtual Reality. https://www.youtube.com/channel/UCYoKN0FOSrHo1qf4ZqlM2CA
While they can offer a taste of VR, mobile headsets don't provide the full experience. They tend to offer three-degrees-of-freedom (3DOF) motion tracking, following your direction but not your position. They also only come with one motion controller, which is also 3DOF-only. You don't get the same immersiveness you do with six-degrees-of-freedom (6DOF) motion tracking and dual motion controllers, which might be why Google and Samsung have been largely quiet lately about their mobile headsets. The Nintendo Labo VR Kit is its own unique case, but it's more of a novelty for Switch owners. https://www.youtube.com/watch?v=xYemnKEKx0c&t=1s
Nintendo's Labo series of games/arts-and-crafts sets for the Nintendo Switch have interested us since the first Labo Variety Kit came out. You build your own controllers with cardboard and play games using the Switch and motion-sensing Joy-Con controllers. Now Nintendo has returned to VR (a field it hasn't set foot in since the ill-fated Virtual Boy) with its fourth Labo package, the Labo VR Kit. https://www.youtube.com/watch?v=xRi-SvU7imU&t=1s
Oculus has both tethered and standalone headsets from the Go, to the Quest, to the Rift S. HTC has the Steam-friendly Vive and the developer-focused Vive Pro. Sony has the PS 4-focused PlayStation VR (that will apparently work with the PlayStation 5 if and when that system comes out), and Microsoft is supporting its Windows Mixed Reality platform with a variety of headsets from different manufacturers. https://www.aliexpress.com/item/Gyros-360-Degree-Metal-Finger-Ring-Holder-for-IPhone-7-6-Samsung-Tablet-Hand-Spinner-Mobile/32816976160.html
Many PlayStation VR games work with the DualShock 4, so you don't even need motion controls. However, those motion controls are where the PlayStation VR lags behind; the headset still uses the PlayStation Move wands from the PlayStation 3 era, and they aren't nearly as capable or comfortable as the Oculus Touch controllers. They're also expensive, and not always included in PlayStation VR bundles. https://www.aliexpress.com/item/-/32793397293.html
One place Microsoft has succeeded in how easy it is to set up its WMR headsets. It uses inside-out tracking, so you won't need to go plug in a bunch of sensors to make sure your headset is being seen. These headsets have built-in cameras and sensors that handle all of that. They'll even track the Windows Mixed Reality controllers, which suffer a bit because they rely on the headset being able to see them clearly to properly track. https://www.youtube.com/watch?v=RSmEWgA_IyM&t=1s
There are few worse feelings than putting on a VR headset and having someone else's sweat drip down your face. That's why, if you're likely to be sharing your headset with others, we'd recommend some sort of cover. The company VR Cover does exactly what it suggests, selling covers for the Rift, Vive, Gear VR and Windows Mixed Reality headsets. You can get a couple of machine-washable covers or, if you prefer, some cheaper disposable ones.
By 1994, Sega released the Sega VR-1 motion simulator arcade attraction, in SegaWorld amusement arcades. It was able to track head movement and featured 3D polygon graphics in stereoscopic 3D, powered by the Sega Model 1 arcade system board. Apple released QuickTime VR, which, despite using the term "VR", was unable to represent virtual reality, and instead displayed 360 photographic panoramas. https://www.youtube.com/watch?v=IapStzmiw1w&t=1s
